A tsunami is a series of waves generated by large undersea disturbances, such as earthquakes or volcanic eruptions. A tsunami can exceed 100 km in wavelength, but measure about 3 m in height. However, as they near shallower water, the wavelength lessens and wave height increases, creating potentially devastating waves in coastal areas. Which of the following best describes the population dynamics in areas of the continental U. S. with the greatest tsunami hazard? A. Though values vary, the population only modestly increased (0-4.9%) between 2000 and 2010 throughout the areas with the greatest tsunami hazard.
B. Though population trends vary throughout the areas with the greatest tsunami hazard, overall there has been a net decrease in population.
C. The central Oregon coast has both the highest tsunami hazard and the highest population increase between 2000 and 2010.
D. The areas with the greatest tsunami risk correspond to areas that have had the greatest population decrease (-46.6% to -5%) from 2000 to 2010.
E. Some of the areas with the highest population increases between 2000 and 2010 (above 14.9%) occur in areas with the greatest tsunami risk.
